         16 . The assembly of  claim 15 , wherein the transferrable holder comprises a carrier and a transfer bar, wherein the through opening in which the transferrable holder is screwed on the threaded rod is arranged in the carrier, and wherein the transfer bar is fixed to the carrier. 
     
     
         17 . The assembly of  claim 15 , further comprising a frame to which the threaded rod is rotationally attached. 
     
     
         18 . The assembly of  claim 17 , wherein the frame comprises a pair of mutually opposite supporting bars. 
     
     
         19 . The assembly of  claim 18 , wherein at least one of the supporting bars includes a bearing, wherein the threaded rod is rotationally attached to the supporting bars by the bearing. 
     
     
         20 . The assembly of  claim 16 , further comprising a frame to which the threaded rod is rotationally attached, wherein the frame comprises a pair of mutually opposite and in parallel arranged side bars configured for guiding movement of the transfer bar in a plane along the longitudinal axis of the threaded rod and for preventing rotation of the transfer bar relative to the frame. 
     
     
         21 . The assembly of  claim 15 , further comprising a guide bar arranged in parallel to the threaded rod, wherein the guide bar extends slidably through a hole in the transferrable holder. 
     
     
         22 . The assembly of  claim 15 , further comprising a motor interconnected with the threaded rod, wherein the motor is configured for driving rotational movement about the longitudinal axis of the threaded rod. 
     
     
         23 . The assembly of  claim 15 , wherein the threaded rod has a pitch of 4 to 12 millimeters. 
     
     
         24 . The assembly of  claim 15 , further comprising a second threaded rod arranged in parallel to the first threaded rod, wherein the transferrable holder comprises a second through opening with an internal thread through which the second threaded rod passes. 
     
     
         25 . An apparatus comprising an air duct member and an assembly for positioning of a regulation membrane in the air duct member, wherein the assembly is arranged at least partially within an interior of the air duct member, wherein the assembly comprises:
 a threaded rod;   a transferrable holder adapted for attaching the regulation membrane thereto and having a through opening with an internal thread, said transferrable holder being screwed on the threaded rod and being movable along a longitudinal axis of the threaded rod by rotation of the threaded rod in the through opening of the transferrable holder, and   at least one element configured for delimiting movement of the transferrable holder along a single plane.   
     
     
         26 . The apparatus of  claim 25 , wherein the threaded rod is arranged so that the longitudinal axis of the threaded rod is arranged in a plane perpendicular to a longitudinal axis of the air duct member. 
     
     
         27 . An apparatus comprising:
 an air duct comprising a distribution duct;   a regulation membrane arranged within the distribution duct; and   an assembly configured for positioning the regulation membrane in the distribution duct, wherein the assembly is arranged at least partially within an interior of the air duct, wherein the assembly comprises:
 a threaded rod, 
 a transferrable holder adapted for attaching the regulation membrane thereto and having a through opening with an internal thread, said transferrable holder being screwed on the threaded rod and being movable along a longitudinal axis of the threaded rod by rotation of the threaded rod in the through opening of the transferrable holder, and 
 at least one element configured for delimiting movement of the transferrable holder along a single plane, 
   wherein one end of the regulation membrane is fixed to the transferrable holder,   wherein the transferrable holder is configured for moving the regulation membrane back and forth between
 a position in which the regulation membrane is arranged adjacent to a first portion of a wall of the distribution duct and 
 a position in which the regulation membrane is arranged adjacent to a second portion of the wall of the distribution duct, wherein the second portion of the wall is opposite the first portion of the wall. 
   
     
     
         28 . The apparatus of  claim 27 , wherein the air duct further comprises an interconnecting duct member, an outlet opening of which is connected to an inlet opening of the distribution duct, wherein the threaded rod with the transferrable holder and the element configured for delimiting the movement of the transferrable holder along a single plane are arranged within the interconnecting duct member, and wherein the regulation membrane has such a shape that, when the transferrable holder is in any end position on the threaded rod, the regulation membrane is arranged adjacent to an internal wall of the interconnecting duct member in a region between the transferrable holder and the inlet opening of the distribution duct.
